The second instance was very likely scripted. Addressing a young audience at Georgetown University this afternoon, the president confessed that his war on coal wasn’t perhaps the sexiest topic for a speech — but nothing else is going on the moment, right? Besides, climate change is the nation’s number one priority out of a long list of top priorities that have drifted in and out of the president’s laser-like focus over the past few years.

When you put it that way, the war on coal is kind of sexy, in a tree-hugging kind of way. But the real heat was behind the podium, where in a repeat of his appearance in Germany, the president removed his suit jacket and encouraged the crowd to do the same, to the sound of screams and cheers.
